Pool handrail is a practical and decorative protrusion that is usually placed on a stair, a slab, a balcony, etc., and is a member for hand-holding along the (top surface) of the railing or the slab, and is used for walking.
Most of the materials are wooden, but there are also metal, plastic, terrazzo, marble and so on. Pool handrail requires safety, firmness, aesthetics, smooth surface and no sharp edges and corners.
Its form can be designed freely, but the width is based on the principle of comfortable hand grip, generally 40~60mm, the widest should not exceed 95mm, and it needs to be continuously set along the length of the ladder and the landing. The interior stair railings take into account the comfort of people when they are gripped. Generally, wooden handrails are used, and the size is related to the body scale. The pool handrail of plastic handrails are also very good, but they are less durable and are not used much now. Metal handrails are excellent in durability and wear resistance, can be processed into various shapes, and are used in public buildings. The disadvantage is that the feeling is poor when used in winter, and people generally do not want to touch it. Therefore, wooden handrails are used more often, and are generally made of hardwood with better wear resistance.
The installation method of the pool handrail is relatively simple. The wooden handrail is generally fixed on the flat steel at the top of the railing with wood screws; the plastic handrail is fastened to the flat steel at the top of the railing by its softness; and the metal handrail can be directly welded with the metal rod.
The pool handrail are generally installed on the side of the ladder and the suspended shaft of the ladder, but when the ladder is wider, the handrail is also required to be placed on the side of the wall, which is called the handrail against the wall. The height of the handrail against the wall is the same as the height of the handrail on the side of the dangling. The general installation method is to reserve a hole in the block wall every 1000 mm, whose size is 100mm×60mm x 60mm, and install the dovetail iron foot, embed it with cement mortar or fine stone concrete, and then install the armrest on the iron. On the feet. If the wall is a concrete or reinforced concrete wall, it is necessary to pre-embed the iron and weld the iron foot to it. In order to ensure the convenience of grasping, the center line of the handrail should be no less than 100mm away from the wall surface.
When the ladder is connected with the platform, or when the ladder is turning, because the height of the ladder is different, the starting position of the step is different, and the height of the railings of each section may be inconsistent. In order to ensure continuous smoothness of the handrail, some treatment is required. The usual practice is to extend the armrests naturally to the platform, so that the armrests are connected at the same height. This will reduce the width of the platform or step back the descending step to make the handrails smooth, but the length of the ladder is increased. When the ladder runs long or short, there is a horizontal railing on the platform, the height of which should not be less than 1050mm. There are several treatment methods for the height difference of the handrail at the turn of the step.
